The host was so nice and kept the house so clean (infact robot cleaned every now and then) . Enough space for a person in the room with a reading table and chair, plug points. Bathroom was not attached but not an issue. Dedicated bathroom for each room. Towel, soap, shampoo are provide. Hot water available all the time. The room was not so sound proof , but it was not a major issue.
Location: Its very close to BTS station. You have a lift to reach the sky train station (BTS) so with luggage no issue. Till the house door you have paved road and can pull your trolley bags. Local market, 7/11 shops , KFC all nearby. No issues on that front. Its near to BKK(Suvarnabhumi) by road too. House is in a lane which is very calm.
Note: the location is bit far from central business area or the major tourist attractions. If you travel by BTS (which is at a bit higher side of the fares) , you may feel its bit expensive to travel all the time from the location. If you are staying far, I suggest you locate close to at least a ferry which is cheap and more enjoyable as a traveller. Or if you are okay with BTS expenses, then I would say okay.
